Application filed November 13, 1918.

To all whom it may concern:

Be it known that I, Josurrr H. POPE, a citizen of the United States,residing at Hamilton in the county of Essex and State of Massachusetts,have invented certain Improvements in HeelGouging and Lip-(JuttingMachines, of which the following description in connection with theaccompanying' drawings, is. a specification, like reference characterson the drawings indicating like parts in the several figures.

This invention relates to cutting machines and is herein illustrated asembodied in a machine for forming a properly shaped concavity inthe'upper surface of a heel preparatory tov attaching it to a shoe andbreasting it.

In the manufacture of certain kinds of I shoes the heels when completeand ready for come to be known in the art attachment to a shoe arecommonly formed with a concavity in their upper faces to fit theconvexity of the heel end of the sole and alsowith a scallop at thebreast end of the heels which is deeper than the concavity. Such-heelsare commonly produced by operating upon them first in a heel gougingmachine which roughs out the concavity and then in a heel compressor,which, besides compressing the heel finishes the formation of theconcavity and forms the scallop. The scallop is produced by the actionof a lip on one die of the mold of the heelcompressor; and from thiscircumstance the scallop has as a lip although it is really theimpression made by the lip of the die. The procedure which has beenoutlined'above possesses the disadvantage that the breast end of theheel is condensed to such an extent by the action of the heel compressorthat the subsequent breasting operation is rendered diflicult; and inorder to avoid this difiiculty manymanufacturers run the gouged heelsthrough a lip cutting machine prior to the. compressing operationin'which case the degree of condensation at the breast end of the heelis less than would otherwise result. v

According to one feature of the present invention the heel gouging andlip cutting are produced in a single operation. In the illustratedmachine the heel is clamped in a holder and moved past a properly shapedrotary cutter so that the heel is traversed by the cutter from: a pointnear the rear of the Specification of Letters Patent.

heel tothe breast edge, means being pro vided for increasing the depthof the cut at the breast end to form the lip or scallop.

Other features of the invention relate .to novel means for clampingandreleasing the heel at the proper times and to means for adgusting themachine to vary the depth of the gouging cut.

Referring to ings,

Figure 1 is'an elevation of a machine in which the present invention isembodied;

Fig. 2 is an elevation of the head of the machine on an enlarged scale;with certain parts broken away. In this figure one heel is shown as justhaving been placed in the machineand another as just having beendelivered from the machine.

Fig. 3 is an elevation looking to the left as the machine is viewed inFigs. 1 and 2 and showing more particularly the mounting of the shaft bywhich the work holders are carried.

Fig. 4: is a perspective of in mechanism.

llounted on the frame 5 a rotary shaft 7 upon the end of which a toothedcutter 9 is mounted, a suction conduit 11 being provided to take awaythe chips and dust. Located below the cutter is a stationary cam-member13 having formedtherein a cam track 15 and having adjustably fastenedthereto by means of a set screw 16 (see Fig. 3) a cam 17. the cam trackthe accompanying drawpart of the drivof the machine is 15 and the cam 17is to guide the work holders in their movement past the cutter and tooperate the clamp which first holds and then releases the heels. The cammember 13 has formed integral with it the bearings for a rotary shaft19, said shaft being thus supported entirely by the cam member. -To theleft of this shaft, as viewed in Fig. 1 or to the rear as viewed in Fig.3, there is a vertical slot 21 in the frame of the machine into whichextends a vertical rib formed on the cam member 13. An adjust-- ingscrew 23 furnishes means for raising and lowering the cam member 13, anda screw bolt 25 extending through a slot 27 in the cam member andthreaded into the frame of p The purpose of The shaft 19 near its rearend carries a spiral gear 29 which meshes with a second spiral gear 31slidingly mounted upon an upright rotary shaft 33 but held from rotationwith respect thereto by means of a key which fits in a keyway 35.Glamped about the hub of the cam member 13'by a pinch bolt 37 is a splitcollar 89 having extending therefrom a yoke 41 which engages the top andbottom faces of the spiral gear 31 to move it vertically when the cammember 13 is adjusted. The upright shaft 33 has at its lower end a wormgear l3 which meshes with a worm 15 on one end of a short shaft 17 theother end of which carries a worm gear-49 in mesh with a worm 51, thelatter being'loose on the driving shaft 53. The cutter shaft 7 is drivenby .a belt 55 which passes around a pulley on the shaft 7 and a pulley57 on the driving shaft 53. A friction clutch, shown in Fig. t, thedetails of which form no part of the present'invenvtion, is controlledby a treadle 59 to connect,

the worm 51 with the driving shaft 53, said latter shaft having theusual tight and loose pulleys and serving through a belt 61 to rotate ablower in a casing 63 which is connected with the suction conduit 11.

Fastened by a set screw 65 to the shaft 19 is acarrier in the form of abar 67 to the ends of which at 69 are .pivoted work holders which areidentical in construction.

1 Each work holder comprises a frame 71 and spring 79 bears, the otherend bearing against a sleeve 81 threaded into a'socket in a clamp 7 3which is pivoted to the frame at 75. Each clamp is generally U-shapedwith the base of the U extending across the rear end of the frame 71 andprovided with a tail .77 against which one 'end of the coiled the frame71. The spring encircles a guide 'rod 83, which extends through a slotin the tail .77, and tends to swing the clamp in a clockwise directionabout its pivot 75. The work supporting face of the work holder lies ina plane parallel to the axis of the shaft 19 passing through the line85: and when the clamp 73 is swung in a clockwise direction about thepivot 75, ears 87 which extend inwardly over the work supporting face ofthe holder are caused to approach 1 said work supporting face andthereby to clamp the work 100 firmly in place on the holder. Referringto Fig. 2, in which the.

direction of rotation of the-carriers are indicated. by the arrow, theclamp of the right-hand holder has just released a heel which has beenoperated upon, while the theshaft 19 to which is pivoted at 91 one clampof the left hand holder is descending to grip a heel which has just beenplaced in the holder. In order to release the work. each clamp has a lug89 projecting toward end of a link 93 theother end of which is pivotedat 95 to a lever 97. This lever is pivoted about the axis of the stud 69and carries at its inner end a roll 99 which is at times engaged bythe'cam 17 to hold the clamp open.

Each work holder, during its revolution,

is moved angularly by a roll 101 which'runs in the cam track 15. Thiscam track is so shaped that-the cutter starts at a point 200 near therear end of the heeland traverses the top of the heel from that point tothe breast edge. Just before the breast-edge is reached a slight rise inthe cam track:15

raises this end of the heel and causes the depth of the cut to beincreased at this point to form the scallop or lip 300.

lines in Fig. 2, and as has been explained its end to rest against agage or stop 103 which isrigid with the holder. As this holder movesupwardly toward the cutter, the roll 99 rides the depth of the 'cutisabruptly increased just before the heel breast is reached.
